NEW JERSEY, A CORPORATION OF DEVICE FOR LOC ATING BOARDS ON BOOK COVERS.

Application filed July 11,

This invention relates a device for use in locating one blank of sheet material upon another and is herein illustrated as embodied in a device for use in locating the boards upon the covers of cases of books.

The case of a book commonly comprises a cover of fabric, leather or imitation leather and two boards, over certain margins of which the cover is folded. In'the manufac ture of such cases two previously cemented boards are placed upon a cover with their outer edges spaced the desired distance from the edges of the cover to provide forthe folding of the coverand with their inner edges spaced apart a distance approximately equal to the thickness of the book for which the case is being made. The majority of cases of books have square corners and thick, stiff boards, such cases being commonly made in large quantities on machines which automatically place the boards on the cover, fold the margin of the cover over the boards and deliver-the completed cases. There are, however, a large number of book cases, such, for example, as those having flexible boards and those having round corners, in the manufacture of which the boards are placed by hand upon the covers preparatory to folding the covers by hand or machine, since bookcases of these kinds cannot be manufactured on the automatic machines referred to above. Commonly, the procedure of locating the boards by hand has been to place a cover upon a table, to place upon the cover a gage in the form of a T square the width of the stem of which is equal to the desired distance between the boards and finally to place the previously cemented boards one-on each side of the stem of the T with-their upper edges in engagement with the top of the T, this procedure requiring considerable skill on the part of the operator and being comparatively slow.

According to one feature of the present invention, there is provided a Support for a stack of blanks such as covers, a gage for Smaller pieces such as the boards, and means for holding the gage in proper position on the top of the stack. In the illustrated device, the edges of the stack of covers are kept in alinement by the walls of a magazine of which the support forms the base, and the walls are suspended from the topof the stack by an end which extends across the stack along the rear edge thereof, there being provided 1927. Serial No. 204,904.

side gages which are pivoted upon the endgage and like it rest upon the top of the stack,

treadle-controlled means being provided for raising the gages, and withthem the walls of the magazine when desired. With this construction, the operator places the previously cemented boards upon the topmost cover of the stack in contact with the end and side gages, presses the boards into place, depresses the treadle to lift the gages, pulls the coverv with theboards attached to it from the stack and releases the treadle, whereupon the gages descend upon the then topmost cover in position to facilitate the location of the next pair of boards. Thus the boards may be rapidly and accurately placed.

It is desirable that the device be capable of use with covers of different sizes. According to another feature of the invention, the walls of the magazine are adjustable to provide for larger and smaller sizes of covers. In the illustrated construction the walls are mounted upon a carrier'and are adjustable in two directions on the carrier.

These and other features of the invention including certain details of construction and combinations of partswill be described as embodied in an illustrative device and pointed out in the appended claims.

Referring now to the accompanying draw- 1ngs, A

Fig. 1 is a perspective of a device in which the present invention is embodied, and

Fig. 2 is a plan view partly in section.

The device comprises a base 3 which sup ports an upright square standard 5. Mounted upon the top of the standard is a support 7 for a stack of covers 100 of thin, flexible sheet material. The support 7 forms the base of a skeleton magazine. The front wall of the magazine is made up of two upright flat bars 9, 11; the rear wall, of the two flat bars 13, 15; the right-hand wall, of the two fiat bars 17, 19; and the left-hand wall of the two flat bars 21, 23. These bars are arranged in four pairs adjacent to the four corners of the support 7, the two members of each pair being integral with eachother.

The bars 9 and 17 are connected near their upper ends by a right-angled portion 25 and at their lower ends by a right-angled portion 27; and the bars 11 and 23 are similarly connected. The bar 9 has at its base a horizontal extension 29 provided witha Slot 31; and the bar 11 has a similar extension 33, provided with a similar slot (not shown). The extensions 29 and 33 overlap each other and their slots are in register. These extensions are horizontally slidable in a guideway in a member 35 and are clamped to said member by a headed bolt the stem of which passes through the slots in the extensions 29, 33, through a hole in the member 35 and has a thun'ib-nut 37 threaded upon its outer end. The member 35 is horizontally slidable upon a carrier in the form of a bar 39 having in one end thereof a slot 41. A cap screw 43 has its stein extending through the slot and threaded into the member 35. \Vith this construction, when the thumb-nut 37 has been loosened, the distance between the upright bars 17 and 23 may be varied to provide for covers of different widths; and when the cap screw 43 has been loosened, the bars 9 and 11 may be moved forwardor back to provide'for covers of different lengths. The two pairs of upright bars 13, 19 and 15, 21 are mounted upon a member 53, which'corresponds to the member 35, said men'rber53, like the member 35, being adjustably mounted upon the carrier 39. An inspection'of Fig. 1 will show that when the thumb-nut 45 (which corresponds to the thunibmut 37) has been loosened, an adjustment may be made for wider or narrower covers; andthat when the cap screw 47 which 'corresponds to the cap screw 43 has been loosened, an adjustment may be made for longer or shorter covers. It will be understood that supports7 of'diiferent sizes may be provided for covers differing in size, these supports "being removably fastened to the top of the standard '5 by a screw 49.

The carrier bar 39 is conveniently made in two parts with a split hub. This split hub has a square hole to receive the square standard 5, and its two parts'are held together by screws,-one of which isshown at 5-1. The'carrier is thus slidable upon the standard 5 and is suspended from the top "of the stack of 'covers in the followingmanner. The member 53,'atthe rear of the device, which corresponds to the member-'35 at the front thereof, has integral with it a bracket '55 which extends first'upwardly and then horizontally. Adjustably -fastened upon the horizontal portion of the bracket 55, by a screw 56 is the short stem of'a flat bar 57, the screw passing through a slot'59 formed in the stem. This bar'57 rests upon thetop of'the stack of covers and its 'frontedge serves as a gage for the ends of the boards 200. Gages 61,63 for the sides o'f'the'boards are pivoted respectively at 65, 67 to the outerends of arms 69, 71, the inner ends of said arms having hubs which are adjus'ta'bly fastened by set screws 73, 75 to a rock-shaft 77. This rockshaft is rotatable in lugs 79 integral with the gage bar 57 and is held from-longitudinal movement by collars 81.

In the operation of the device the covers, after the boards have been placed upon them and the gages slightly raised, are pulled one of these bars are substantially flush with the top of thestack. In order to lift the carrier 39, and with it the walls of the magazine and the gages for the boards, when a cover is to be pulled from the top o'fthe stack or when a new stack of covers is to be placed upon the support 7, a lever 81, pivoted near its middle at 83 to a post ris'ing from the ba-se of themachine, has its inner end extending beneath the hub of the ca 'rier 39, its outer end being connected with the upper end-of a-treadle rod 82 to the lower end of which a 'tr'eadle (not shown) is connected.

Theside gages 61 and 63 are raised when the treadle is depressedby reason of bars 85, 87 fast respectively to'the gages. The bar 85 rests upon a support in the form, of a bar 89 adjustably fastened in :angular position to the upright bar 17 of the magazineby a screw 91. The bar '87 rests upona similar support 93 carriedby the-upnightbar23 of the magazine. The supports 89 and 93 vare adjusted into such positions that the side gagestil, 63

normally rest lightly upon the top of the stack of covers 100.

Assuming that a stack of covers has been placed upon the support 7, the-operation of the device is as follows:

Two boards, which have been properly cemented, are p'lacedupon'thetopnrosteover in the positions shown in the drawings with their upper edges as viewed in Fig. 2 in contact with the gage 57 and their outer side edges in contact respectively with the side gages 61, 63, and are pressed against the cover. Common-1y the boards each have a stripe of cement on their under ifaces extending along their adjacent margins, .in which 'casethe operator-merely d'raws his forefingers the bars 9, 11. The treadle is then released whereupon the carrier, with-all its supported parts,'descends until=the gages rest upon the then topmost coverof the stack, whereupon the operation described above may be repeated.
